Abstract

The invention discloses a test device of temperature rising of a motor. The test device comprises an accompany test motor and a tested motor which rotates through connection with the accompany test motor. The test device also comprises a large-power variable-resistance cabinet connected with the output end of the tested motor. The output end of the tested motor is connected with a first power tester. The input end of the accompany test motor is connected with a control frequency converter. In the test device, input control of a permanent magnetic motor is achieved by use of a set of control frequency converters; load of the motor is simulated through the large-power variable-resistance cabinet; control is quite simple; test difficulty is reduced; a pure resistance load mode is actually and precisely simulated through resistance adjustment of the resistance cabinet; the load is easily adjusted at anytime; cost of the test device is reduced; out of step, sudden stopping and running away of a vehicle does not easily occur; test safety is improved; temperature rising requirements of the permanent magnetic motor are met; the pure resistance load is formed in the system, so the test results are nearer to actual working conditions; and technical problems of high cost, big control difficulty and quite poor system safety of the current motor temperature rising test are effectively solved.

Description

technical field [0001] The invention relates to the technical field of motor testing, and more specifically relates to a motor temperature rise test device for a high-power permanent magnet traction motor temperature rise test. Background technique [0002] Permanent magnet motors have the advantages of light weight, simple structure, low loss, and high efficiency, and are widely used in various fields such as electric vehicles, rail transit, wind power generation, aerospace, and daily life. With the increasing maturity of high-speed rail technology, the research and development of high-power permanent magnet traction motors is imminent. However, in the process of developing high-power permanent magnet motors, the test ability is the technical bottleneck of its design and development, and the temperature rise test is an important assessment item for its design. . [0003] At present, people usually use the motor-to-drag method to carry out the temperature rise test of the h...
